Build Your Own JavaScript Methods with Hitesh & Piyush's Dev Team! 🚀

🌟Welcome to Team Hitesh & Piyush Dev Academy!

Hey there, future JavaScript champ! 🏆 Imagine Hitesh & Piyush Sir are creating a legendary dev team 💻⚡, and they want YOU to be a part of it! But before you join, you need to train like a true coding warrior. Ready? Let’s go! 🚀

🤔 What is a Polyfill?

Imagine you're in a dev team, and one member doesn’t know a certain skill. To make the team stronger, you teach them! That’s exactly what a polyfill does—it helps JavaScript understand a method it doesn’t know!

Today, we’ll teach JavaScript some new tricks by building our own superhero methods! 🧙‍♂️🔥

🚀 Mission 1: myMap() → "Hitesh Sir Trains Every Dev!"

Every dev in the team must level up! Hitesh Sir ensures each one gets trained and returns stronger. That’s what map() does—it transforms each element in an array.

Array.prototype.myMap = function(callback) {
  let result = [];
  for (let i = 0; i < this.length; i++) {
    result.push(callback(this[i], i, this));
  }
  return result;
};

🎯 Example:

let skills = ["HTML", "CSS", "JS"];
let upgradedSkills = skills.myMap(skill => skill + "++");
console.log(upgradedSkills); // ["HTML++", "CSS++", "JS++"] Now you have a super power ++

🌟 Mission 2: myForEach() → "Akash Sir, Mukul Sir and All TA’s Gives Individual Coaching!"

All TA’s are personally guides each dev and gives feedback. That’s what forEach() does—it goes through every element.

Array.prototype.myForEach = function(callback) {
  for (let i = 0; i < this.length; i++) {
    callback(this[i], i, this);
  }
};

🎯 Example:

let developers = ["Ankit", "Renil", "Krunal"];
developers.myForEach(dev => console.log(dev + " is improving!"));
// Ankit is improving!
// Renil is improving!
// Krunal is improving!
// After the massive support from each other all are improving 💪

🔍 Mission 3: myFilter() → "Only the Best Coders Stay in the Team For Open-Source FreeAPI!"

Not everyone makes it! Only the best coders get selected for the open-source contribution in FreeAPI peoduct. filter() picks the best from an array.

Array.prototype.myFilter = function(callback) {
  let result = [];
  for (let i = 0; i < this.length; i++) {
    if (callback(this[i], i, this)) {
      result.push(this[i]);
    }
  }
  return result;
};

🎯 Example:

let scores = [30, 50, 80, 100];
let qualified = scores.myFilter(score => score > 50); // for qualification took above 50+ that's the bar
console.log(qualified); // [80, 100] Cudo's you are qualified for contribution

🛠 Mission 4: myReduce() → "Building the Ultimate Dev Skillset!"

A great team isn’t about individuals—it’s about the combined knowledge! reduce() takes multiple values and combines them into one.

Array.prototype.myReduce = function(callback, initialValue) {
  let accumulator = initialValue;
  for (let i = 0; i < this.length; i++) {
    accumulator = callback(accumulator, this[i], i, this);
  }
  return accumulator;
};

🎯 Example:

let scores = [20, 60, 40, 80];
let totalScores = scores.myReduce((total, scr) => total + scr, 0);
console.log(totalScores); // 200 At the end teamwork lead's the scores 🔥

🔍 Mission 5: myFind() → "Finding the Lead Developer(Superhero Dev)!"

Every dev team needs a lead developer the superhero of the team 🦸‍♂️! find() searches for the first element that matches a condition.

Array.prototype.myFind = function(callback) {
  for (let i = 0; i < this.length; i++) {
    if (callback(this[i], i, this)) {
      return this[i];
    }
  }
  return undefined;
};

🎯 Example:

let developers = [
  { name: "Sujal", role: "Frontend" },
  { name: "Vaibhav", role: "Backend" },
  { name: "Renil", role: "Fullstack" }
];

let leadDev = developers.myFind(dev => dev.role === "Fullstack"); // Genius get's the lead role
console.log(leadDev); // { name: "Renil", role: "Fullstack" }

🦸‍♀️ Mission 6: mySome() → "Not Everyone Makes It, But the Few Heroes Will!"

Sometimes not everyone in the team is a hero, but there will always be a few champions who will make it! some(). checks if any element in the array matches a condition.

Array.prototype.mySome = function(callback) {
  for (let i = 0; i < this.length; i++) {
    if (callback(this[i], i, this)) {
      return true;
    }
  }
  return false;
};

🎯 Example:

let heroes = [false, false, true, false];
let anyHero = heroes.mySome(hero => hero); 
console.log(anyHero); // true, because one hero exists in the team 🦸‍♂️

⚡ Mission 7: myEvery() → "Every Hero in the Team Must Be Strong!"

In a great team, every hero needs to be strong and have some unique strength. every() checks if all elements in the array match a condition.

Array.prototype.myEvery = function(callback) {
  for (let i = 0; i < this.length; i++) {
    if (!callback(this[i], i, this)) {
      return false;
    }
  }
  return true;
};

🎯 Example:

let skilled = [true, true, true, true];
let allHeroes = skilled.myEvery(hero => hero); 
console.log(allHeroes); // true, because all heroes are skilled and strong 💪

🔍 Mission 8: myIncludes() → "Checking for Team Members!"

In any dev team, you need to check if someone is already part of the squad. includes() checks if an element exists in an array.

Array.prototype.myIncludes = function(value) {
  for (let i = 0; i < this.length; i++) {
    if (this[i] === value) {
      return true;
    }
  }
  return false;
};

🎯 Example:

let developers = ["Vaibhav", "Renil", "Krunal"];
let isInTeam = developers.myIncludes("Krunal"); 
console.log(isInTeam); // true, Krunal is part of the team!

💪 Mission 9: mySort() → "Sorting the Team Based on Skills!"

Every dev needs to be in the right position. sort() helps arrange the team based on their skill levels.

Array.prototype.mySort = function(callback) {
  let sortedArray = [...this];
  for (let i = 0; i < sortedArray.length; i++) {
    for (let j = 0; j < sortedArray.length - 1 - i; j++) {
      if (callback(sortedArray[j], sortedArray[j + 1]) > 0) {
        let temp = sortedArray[j];
        sortedArray[j] = sortedArray[j + 1];
        sortedArray[j + 1] = temp;
      }
    }
  }
  return sortedArray;
};

🎯 Example:

let skills = [90, 70, 50, 100];
let sortedSkills = skills.mySort((a, b) => a - b); // Sorting by skill levels
console.log(sortedSkills); // [50, 70, 90, 100]

🌟 Mission 10: myConcat() → "Uniting Powers for the Ultimate Team!"

Sometimes the team needs to combine forces with another team to grow stronger and build a true software for real world solution. concat() is all about uniting multiple arrays into one powerful array!

Array.prototype.myConcat = function(...arrays) {
  let result = [...this];
  for (let array of arrays) {
    result.push(...array);
  }
  return result;
};

🎯 Example:

let teamNewbie = ["Vaibhav", "Renil"];
let teamProCoders = ["Akash", "Mukul"];
let teamLegendryCoders = ["Hitesh", "Piyush"]; // The OG ones (Super Duper Heroes)

let ultimateTeam = teamNewbie.myConcat(teamProCoders, teamLegendryCoders);
console.log(ultimateTeam); // ["Vaibhav", "Renil", "Akash", "Mukul", "Hitesh", "Piyush"]
